Granite composite sink- thoughts and opinions

My wife really likes these type of sinks having seen them at Lowes. I am partial to a cast iron which is tried and true. Her biggest objection to a black cast iron sink is the high gloss. Her first choice is a low gloss black sink and doesn't care about the material other than that.

So how do these granite composite sinks hold up? I have read a variety of opinions about them on another website.
